And, of course, there’s also a cross-game promotion in the form of summer camp-themed activities. Reminiscent of the Great Steam Treasure Hunt from last year, and the Potato Sack ARG, playing Steam games and completing different tasks in them, thus earning special summer camp achievements will get you summer camp tickets. Get 3 of these, and you can redeem prizes in the form of in-game content from the summer camp Prize Booth. Of interest to Valve fans are the TF2 Summer Shades, and the Portal 2 Goo Gear Snorkels. You can even keep track of your tickets and redeemed prizes on your profile! The prize system seems to have been set up in such a way that you’ll only be able to get a maximum of 4 prizes, so choose them wisely!

But just like the Great Steam Treasure Hunt, there’s also a grand prize involved!

100 lucky campers will get the top 10 games on their Steam Wishlist (in a burst of creativity, we decided to call this the “Grand Prize Giveaway”). First, create and organize your Steam Wishlist. For every Prize Ticket you earn, you will be entered into the Grand Prize Giveaway. Your entries are tracked here and on your Steam Profile page. We’ll draw the winners at the conclusion of the Steam Summer Camp Sale.
